My doctor prescribed this ointment for Impitego ... I had redness with lots of annoying itching around my mouth and cracked lips ( I thought I got too much sun, as I was just home after two weeks at the beach). I have been on it for 5 days now and still have lots of redness and some itching... how long does it take to work? PS - I never had the oozing or bumps of Impitego--- Could I possibly have been misdiagnosed? - C.
